HERBERT OER', a; citizen of the United States, residing at' Toledo, in the county of Lucas and State v Nut-Lock, of njhichthe following is a speciof' Ohio, have 'invented a .new and useful My invention relates to improvements in looking-devices in which it issought to lock a nut, cone, cup, or other body Working on a threaded surface in aV permanent and iixed position; andthe objects ofmy improvement j afec-1st., to ermit ofthe tight lockingof a adjustably lockv a nutor other threaded ,body

the drawingsl 1 designates a" screw threaded bolt,- suchv as is usual in vmachine practice. 'This'bolt .has a right hand thread 5,-and 1s provldedwith adiametric key open- -ing 7, for the lreception of a pin or key 6.

Upon the bolt 1 there is threaded. a .sectlonal nut, comprising the inner section 2,

and the Outer section 3. The inner sectionl 2 has a portion with squared faces for the use 'of' a wrench and an outer cylindrical'portion` provided with alet hand threadlt.

Section 3 vis referably provided with .squared fac-es for t e use of a Wrench, and has an outer end portion With an axial bore per- ,mitting4 it4 to ass 'over and' not engage the thread of the Lk) olt and aninner end portion threaded to engage thel outer` cylindrical-l portion of section 2. The squared faces upon section 2 and 3 are not an essentla'l Vpart of my invention.

Through the outer portion having the .axial bore, the section 3 is provided With a diametric key opening 8 adapted to bebrought into register with, the opening 7 of the bolt 1 to permit the insertion of the pin or'key.

Thus constructed the operation yol" my in- :vention-is asfollowsz-The section 2 carry-l ing the section 3 .fully engaged u on it, is

screwed up onthe bolt 1, until t e nut is tighty against the object to be held. The section 3 is then unscreWed on the thread 4, and" oWin to the difference in the direction of the t eads 4 and 5, the tendency of this un- -screwing is to still further tighten the section 2 against theobject, until the key openings 8 in vEhe section 3 register with the key opening 47"in-the bolt' 1, at which time the key 6 is inthe partsfare thereby ockedagainst any roltation. -'Asthe .outer section 3" is held immovable onQtheb'olt-bythe keyl 4, the inner 'see'tiongisfheldimmovable by the oppositionioits' tlieadsftand 5, vand cannot move either.forwardforfbakward, as any endency' tomove ineithefrdirection {on the one -thread vWould' be"polintel'racte'd` a, tendency to .move in ther oppositedirection on 'the other thread .of `sectional'nut?constructed in accordance .'With. my.invention. The operation of'this modified form' "is the 'same -asfheretofore de- -scribedfz placed in position and that thefse'ctionmay thereafter be brought into. position by pass ing it over thebolt and screwing it up onthe section* 2, untilthe key openings are in re ister, vlalthdugh-.the `method first set forth 1s. preferable.

.-In Figs. 3 and 'arelshow'na modiiiedform l. `v j Itis Obvious that the section 2 may be The sections of the nut and the bolt-are to be designed for" a' certain range of adjust-- ment, suited to the requirements of the rio INS... ta"- -ciples of construct ing of a cone, cup, or other threaded body7 Awork;' the lengths of the threaded ,portion of section 3 and of that corresponding to it in sectlon 2 determining said range of adjustment;.the dimensions of said sections are'toy be such that several of said threads will remain engaged when the nut is locked. Itis apparent also that the same rin- 'on may be used for oekon a threaded surface, in any position that may be desired and I therefore do not limit myself t'o the application of my invention as shown and described.

While the outer end portion of section 2 is V preferably threaded y'reversely to the thread the bolt1 it is manifest'that if lsaid outer end portion is provided with anythread such that the enga ement of section 2 on both the ing vof section 2 a locking ofthe result when the key is inserted, s

prevent the rotation of, said section. "I 4therefore do not limit myself in the constructhread ofthe olt and thethread of the inner end portion of the outer section would cause an interference of saidthreads to the revolvarts -`will cient to tiony of my inventionlto the use of an inner section having. 011e orti'onreversely threadof a sectional nut` comprising tion 'having'an interior-threa ed with res ectto t e other.

' WhatIc aim to be neviT is:- v 1. Thecomb'inationwith threaded body,

an inner secthreaded body and an yfouter endl portion threaded so that ,the threads cross over With- 'out engaging the threads ofthe threaded body, anouter section having an axial bore permittingbit to pass over and not engage the Athreaded vamitiee body.
